Dual Variable Valve Timing with intelligence (VVT-i) optimizes both the intake and exhaust valve timing throughout the rpm range, depending on engine and driving conditions. The system continuously monitors the engine’s speed and load to respond to the driver’s demands. This helps provide improved fuel efficiency, lower exhaust emissions and optimum power across all driving ranges. Torque is increased at lower speeds for better thrust. And power is boosted at higher speeds for better acceleration.
